摘　　要：黄河天桥水电站除险加固后新增两孔泄洪闸和四孔排沙底孔,为保持水库的设计有效库容,充分发挥水电站的发电效益,对水电站运行调度方式进行了研究。通过实测资料分析,研究了天桥水电站排沙、排凌运用指标。通过数学模型计算,分析论证了不同方案下库区的冲刷和恢复库容效果,计算了不同方案下的发电量,提出了天桥水电站除险加固后运行调度方式。Two sluice gates and four bottom holes for sediment discharging are newly built in the reinforcement of Tianqiao Hydropower Station. To keep the designed effective reservoir capacity and make full use of power generation potential, the operation mode of station after reinforcement is studied. Based on measured data, the operation index of sediment discharged and ice discharged are studied. After calculation by mathematical model, the effects of scouring and reservoir capacity recovery under different schemes are analyzed and demonstrated, and the power generations are also calculated. The operation mode of Tianqiao Hydropower Station after reinforcement is finally proposed.
